Abstract
The effect of lanolin paste containing 1000ppm of 15 βOH GA15, 15 β0H GA24 and 15 βOH GA9(GA45) on fruit set and development of three different kinds of pearcultivars(‘Shinseiki’-Pyrus serotina, ‘Yali’-Pyrus ussuriensis and ‘Passe Crassane’-Pyrus communis) was compared with 1000ppm of GA4+7. In general, an exogenous application of GA4+7 3 weeks after full bloom was the most effective at bringing about fruit set of embryo-removed pears, followed by GA45, 15 βOH GA15 and 15 βOH GA24. There were no striking asymmetric growth in any cultivar when the lanolin paste containing GA was applied to one side of the surface of seeded fruit. Fruit development in terms of fruit size and weight was most pronounced in all pear cultivars when GA4+7 was applied. Extracts from immature seeds of three pear cultivars were separated by paper chromatography with a developing solvent systems of iso-PrOH:NH4OH:H2O (10:1:1v/v). Using either the dwarf rice seedling or barley half-seed bioassay, GA-like activities were detected in two Rf zones near 0.7 and 0.9. Later, the eluate from near Rf zone 0.7 was identified as GA3(published elsewhere).
